Without some more data, it is impossible to tell, but go to Radio Shack, and pony up about $25 bucks for their hand held dB meter. Not the do all end all in accuracy, but it will give you a ball park figure.

 

I've seen similar stuff hit 140 db. Each system varies though.

 

I agree. There are way to many variables to be able to tell how you will actually do. best is to have it metered by a shop...most will do it for a small fee.
